    Default My POP3 services (110) is stucked.

    Dear all. I have some problems with my Zimbra Server.



    My Server Information
    My zimbra version is : Release 5.0.5_GA_2201.UBUNTU6 UBUNTU7 FOSS edition
    Server : Linux Ubuntu 7.10


    Problem and chronologies:

    First of all, my server haven't been in problem since first time running (already 365 days). After those 365 days , I am asked to renew Self Signed Certificate. Then I renewed that certificate and restart the Zimbra service by doing "Zmcontrol stop/start" command without rebooting the server.

    The certificaiton renewal processi is successfull but the next day my POP3 service is stucked. I tried to telnet from my client to mymailserver.com port 110 but it is stucked. Then i tried to telnet from localhost, but i got the same result which is also stucked. The error message is :


    Trying 127.0.0.1...
    Connected to localhost.
    Escape character is '^]'.



    Then I restarted the zimbra service by doing command "zmcontrol stop/start" . After I restarting the service, my POP3 service isn't stucked anymore. I tried to telnet to mymailserver.com port 110 and I don't get the error message anymore (succesffully telneting):

    +OK mymailserver.com Zimbra POP3 server ready


    But, after one day that problem (POP3 service got stucked) occured again. Then the problem is solved when I restarted the Zimbra service again. But the next day occured again. What would you think about this problem ?

    Welcome to the forums

    You should really look to upgrade to the latest release.

    Have you checked your logfiles for any error messages ?

    Hi uxbod, I think the problem is not laid on the update.
    Which logfiles do you mean? /var/log/messages? if this log, there is nothing suspicious.

    Hi luthor,

    IS it delay in the banner or does banner doesnt turnup atall ? As ubox said /var/log/zimbra.log , does it report anything when you telnet ?

    Seeing imapproxy logs at startup will also be uselfull. Just start the service seperately using zmproxyctl restart. Check if any warnings or errors ?

    Hi veronica, thanks for replying. It is caused by the delay. The banner doesn;t show up for couple minutes. AFter that, I tried using outlook to test the pop3 service but failed.

    After that, I restarted the zimbra service then the service is running well.

    I also have checked the /var/log/zimbra.log , but there is any errors when I do the telnet (when it is error)

    ANy solution ?
